1 Describe and Evaluate the Cognitive Treatment for Schizophrenia

2 What is CBT? Cognitive behavioural therapy (CBT) is based on the idea that most unwanted thinking patterns, and emotional and behavioural reactions are learnt over a long period of time.

3 The CBT approach to treatment of schizophrenia differs slightly from conventional CBT methods.
The aims of this therapy are as follows: To challenge and modify delusory beliefs To help the patient to identify delusions To challenge those delusions by looking at evidence To help the patient to begin to test the reality of the evidence

4 An example of a delusional belief
Event Overhearing someone saying “I know what’s on your mind” Interpretation Everyone can read my thoughts Feeling Paranoid, scared and believing that others will attack me for my thoughts Behaviour Take evasive action – avoiding situations that will bring me into contact with others

5 eg – thinking that people what to kill you.
For example, you may be taught to recognize examples of delusional thinking in yourself. eg – thinking that people what to kill you. You may then receive help and advice about how you can avoid acting on these thoughts. eg – Rationalizing that people have no reason to want to hurt you. Encouraging you to engage with people in meaningful ways. Allowing opportunities to practice these new skills and share your experiences and reflect on how it felt to engage in positive social interactions.

6 Most people will require between eight to 20 sessions of CBT over the space of six to 12 months. CBT sessions usually last for about an hour.

7 This type of treatment has been shown to be effective for reducing the positive symptoms of schizophrenia, for reducing relapse and for enhancing recovery when schizophrenia is diagnosed early.

8 Cognitive Treatment Sensky et al. (2000)
Aim To compare cognitive behavioural therapy (CBT) with non-specific befriending interventions for patients with schizophrenia Design A randomized controlled design. Patients were allocated to one of two groups: a cognitive behavioural therapy group. a non-specific befriending control group.

9 Participants Procedure 90 patients.
57 from clinics in Newcastle, Cleveland and Durham and 33 from London. They had diagnoses of schizophrenia that had not responded to medication. Aged 16–60 years. Procedure Patients were allocated to one of two groups. Both interventions were delivered by two experienced nurses who received regular supervision. Patients were assessed by blind raters at baseline. after treatment (lasting up to 9 months). at a 9-month follow-up evaluation. They were assessed on measures including the Comprehensive Psychiatric Rating Scale, the Scale for Assessment of Negative Symptoms, plus a depression rating scale. Patients continued to receive routine care throughout the study. The patients received a mean of 19 individual treatment sessions over 9 months.

10 Cognitive behavioural therapy condition
A normal routine of CBT was used: initially engaging with patient psycho education developing a reason for the behaviour Cognitive and behavioural interventions treatment of other disorders such as depression Reducing relapse by planning ahead

11 CBT Strategies Used Specific techniques for positive symptoms of schizophrenia were used: critical analysis of beliefs about auditory hallucinations. patients were helped to change their beliefs. patients taught coping strategies to deal with the voices. Delusions and thought disorders were also addressed using cognitive strategies.

12 Befriending condition
The patients had the same time allocation at the same intervals as patients in the CBT condition. The therapists were empathic and non-directive. There was no attempt at therapy: The sessions focused on hobbies, sports and current affairs.

13 Findings Both interventions resulted in significant reductions in positive and negative symptoms and depression. After treatment there was no significant difference between the two groups. At the nine-month follow-up evaluation, patients who had received cognitive therapy showed greater improvements on all measures. They had improved, while the befriending group had lost some of the benefits.

14 Evaluate the research:
Conclusions Cognitive behavioural therapy is effective in treating negative as well as positive symptoms in schizophrenia resistant to standard antipsychotic drugs. Its efficacy is sustained for at least nine months. Evaluate the research:

15 Evaluation of CBT for Schizophrenia
Shown to be incredibly effective Allows people to function more normally with symptoms, preventing Learned symptoms from developing. Can be used in conjunction with other therapies Improves symptoms, recovery and relapse rates No side effects Not very rational to teach patients to see life through rose coloured spectacles Doesn’t work for everybody Expensive and time consuming

16 Read the Case study and answer the questions on the worksheet

17 Extension Apply your knowledge:
You have a friend that you believe has schizophrenia. You have been asked to explain to them why they might have schizophrenia. They also ask you about which treatments you would recommend. Which explanations / treatments would you share with them? Are there any that you would leave out?
